Nokia C3-00 uses Symbian S40, and unfortunately there is no whatsapp or Skype for it.

WhatsApp can only be on Nokia Symbian S60.

The Nokia C3 is based on the 'old' Symbian S40 operating system and will not support WhatsApp ... and Skype !!!

There are many other Nokia applications that will not work under Symbian S40 for the Nokia C3 range.

Hope it clarifies the situation for the many Nokia C3 users!
